The long path to perfection.
The upgrade has been again a real improvement, but something still lacks. The sincronization with dropbox is better but still dangerous if you have two devices connected. Also, the internet connection is still cause of crash, when the app is used with others (but probably its due to iOs). Again, it would be good some more color for grammar, and the possibility to open also .bib files in another app (dropbox!).
In any case, its the best TeX app for iOs.
